What the programme covers
Feasibility protects both buyer and source organization from expensive processing against an ambiguous or impossible specification. It should identify the limiting requirement, not merely return a large preliminary file count.
What a useful specification includes
A defensible request defines the clinical task, source evidence and acceptance criteria before patient-level data moves. The exact fields and thresholds depend on the intended model claim.
- Clinical task and unit of analysis
- Inclusion, exclusion and control definitions
- Required imaging series and acquisition constraints
- Ground truth and clinical linkage
- Privacy, geography and permitted-use requirements
- Acceptance metrics, volume and schedule
Quality and validation controls
A representative sample can test series classification, linkage, privacy and label assumptions. Sampling results must not be extrapolated without recording the method and uncertainty.
- Patient versus study versus series counts
- Required-field completeness
- Image and report linkage
- Ground-truth strength and review burden
- Permission, privacy and delivery dependencies
Availability, rights and delivery
The feasibility record should make the go, revise or decline decision auditable. It does not itself authorize patient-level data release.
Public pages describe a sourcing and engineering capability, not guaranteed ready inventory. Each release remains subject to verified programme inventory, programme-specific authorization, privacy review, technical acceptance and buyer licence terms.
Questions, answered directly.
Why not begin with a full archive export?+
Aggregate queries and samples can expose specification problems before unnecessary patient-level processing.
What can make a cohort infeasible?+
Insufficient eligible cases, missing sequences, weak ground truth, incomplete follow-up, permission limits or an incompatible timeline can each be limiting.
Can the buyer trade one requirement for another?+
Yes. A feasibility study should expose trade-offs such as volume versus ground-truth strength or protocol precision.
Is inventory under verification ready to order?+
No. It remains a separate status until required source, evidence and authority checks are complete.
